Hi, I recently began re-assembling a computer I used to use about a year ago. The hard drive is empty. During bootup, it loads keyboard, mouse, floppy drive, but neither my hard drive or my cd-rom. I can boot from the floppy but I have nowhere to install an OS to, or to install one FROM for that matter. I have swapped out the ribbons and cd-roms but they still are not recognized during bootup. When the bios is opened, it doesn't show anything under the primary slave/master or the secondary slave/master. I really hope its not the MoBo, but possibly? Thank you.
